How to restore an ipod without updating Sex cam mit ps3
Whenever you upgrade or downgrade your i Phone, i Pod Touch or i Pad, new SHSH blobs have to be generated because one of the parts to the SHSH formula is the firmware version.
In order to prevent firmware restores Apple only signs one firmware version at a time, which is obviously the latest firmware version available.
To do this you can use tools like Tiny Umbrella (download) and i Faith (download).
It is important to keep in mind that these tools can even save the SHSH blobs of non-Jailbroken devices.
If you try to restore to a lower firmware version, you will get an error because Apple is not signing that specific firmware version anymore.
What is happening is Apple refuses to generate the new hash during the downgrade, meaning the new SHSH blobs cannot be generated.
Once you have your SHSH blobs signed, as stated previously, if you upgrade to a new firmware version and decide you don’t like it you can downgrade back to the firmware version which you have saved SHSH blobs for.
There is unfortunately some restrictions that need to be kept in mind though.
Meaning you had to have saved your SHSH blobs for the firmware version you are trying to downgrade to, or downgrading will not work.
If you are looking for more information on how to save SHSH blobs and APTickets you will want to visit our How To Save SHSH Blobs section.
Note: Keep in mind that if you find a guide for a previous firmware version and don’t see one for your current situation, most of the time these guides are all-purpose.
APTickets are much more secure however, because when you try to restore or upgrade your i Phone, i Pod Touch or i Pad a request is sent to Apple’s servers to confirm the APTicket.
Unlike SHSH blobs which would submit the same one already stored on the server, a brand new APTicket is generated using a random string.
The only exception to this is that i Pad 2 owners with any saved i OS 4 firmware generation SHSH blobs can downgrade to to any firmware that they also have saved SHSH blobs for.
